An except of how volcano research and monitoring can save lives
Volcanic eruptions come with a variety of hazards, depending on the
type of volcano and its magma. Some have effusive eruptions, where
lava flows constantly, while others can expel large clouds of
fragments of magma and gases – volcanic ash – into the atmosphere. For
some of the most powerful eruptions, these ash clouds can rise tens of
kilometers into the air and travel thousands of kilometers. This is
what has happened on the island of St Vincent and the Grenadines,
after a new eruption was confirmed at La Soufriere volcano on April 9
2021. The explosive eruption, the first since the volcano last erupted
in 1979, produced an ash plume of about six kilometers, which was also
seen in satellite images. The eruption prompted the evacuation of
about 20,000 people, with no casualties. This was made possible thanks
to our improved understanding of how volcanoes work and new advances
in volcano monitoring.
